So I've looked at several threads, and I'm sure there are a lot more I could read, but I want to know if there is a hard and fast rule to deciding whether one should divide a project up or not. I have a project starting up right now and I want to know what others are doing. I've elected to keep everything as one single model despite there being three different buildings. The buildings aren't very big so I figured I could manage the project with worksets instead of creating separate models and linking them in to another file. How do others deal with documenting three different models? Do you just link them in and document from that file? Or do you document from each individual file? It seems like one file is less confusing for users, and I don't have to make sure all the files are documented the same way. Any thoughts?
